Unless one of the sparkplugs was changed just before starting it up
that time, that seems unlikely.

You didn't give us very much info about the problem... Was it running
badly or just making noise? Can you describe the noise at all? Are you
mechanically inclined enough to at least remove the spark plugs and
accessory belts and run the starter? That will narrow things way down
with a minimum of effort. (A lot of horrible "engine" noises turn out
to be failed alternators, water pumps, etc...)

Update: She had a nearby mechanic (not the usual one) take a look at the
car. He pulled the plugs and in fact, one WAS broken. That's as far as it
went. He said "No way to determine damage without major teardown - $1500 or
so." Our usual mechanic says "More like $2500 - not worth it for a car with
book value of $3000-ish". The latter guy is probably being cautious and
preparing her for worst case scenario.

What a mess.

Where was the plug broken, what part of it, did it melt, what is the
plugs color, did you try a new one just to see what happens or try a
compression test. So post a photo of it, you can tell alot about a
cars overall running condition and age by looking at a plug. A 15 $
compression tester and a new plug will tell you alot.
